Monroe and State of New York, haveinvented certain new and usefulImprovements in Photographic and Developing Apparatus, of which thefollowing is a specification.

This invention relates to photographic, Y

printing and developing apparatus having the combined functions ofexposing the film to the action of light and of thereafter treating thesame, the said apparatus being here shown as motormeans actuated by themechanism for controlling the motor.

An object of this invention is to produce a photographic and developingapparatus in operative relation to each other, the said developingapparatus having a receptacle for fluid, which fluid. will act on thecoated surface of the film and with relation to which a rotary member,preferably in the form of a drum, is supported and adapted to displacethe fluid to such an extent as to make it possible to employ a minimumquantity of fluid for the purpose of immersing the film, means beingalso provided for delivering film to the receptacle and for removing ittherefrom.

.It is furthermore an object of this invention to provide a receptaclein operative re lation .to the means for removing the film from thefirst mentioned receptacle, the second mentioned receptacle beingadapted to contain liquid preferably of the character of fixing fluid.In order to cause the film to enter the second mentioned receptacle andto lie flat therein after it has been released by the means for removingthe belt from the first mentioned receptacle, I supply the secondmentioned receptacle with a spraying attachment designed to force liquidand I utilize the force of such liquid to cause the film to travel inthe second mentioned receptacle while, at the same time, acting on saidfilm to cause it to lie fiat in the liquid contained in the secondmentioned receptacle, and furthermore an object of the invention is toprovide mechanism for spreading the film and mechanism for immersing thefilm. A still further-object of this invention is to provide a motor fordriving the appara- Speciflcation of Letters Patent;

tus-and' means actuated b a part of the v apparatus for. controlling t emotor. Furthermore, .an object of this invention is to provide aconveyor or carrying device preferably comprising an apron or belt withwhich a flexible device such as a chain or the like coacts to retain thefilm on an apron or belt while the said film is being subjected to theaction of developing .or other fluid. 1 W1th the foregoing and otherobjects in view, the invention consists in the details of constructionand in the arrangement and combination of parts to be hereinafter morefully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification,

wherein like characters denote corresponding parts in the several views,in which- Figure 1 illustrates-a view in side elevation of aphotographic and developing apparatus embodying the invention; Fig; 2illustrates a' view inelevation of a part of the interior mechanism;Fig. 3 illustrates an elevation of the interior mechanism fromtheopposite side; Fig. l'illllStlfltGS a portion of the apparatus partlyin section; [Fig 5 illustrates a view in elevation showing the end ofthe apparatus, a partthereof being in section; Fig. '6 illustrates adetail plan of the rear of the apparatus; Fig. 7 illustrates a sideelevation of a portion of the rear ofthe apparatus; Fig. 8 illustrates adetail plan view of they pump and sprinkler;

In these drawings A indicates a casing for the developing apparatuscovered by a magazine B, adapted to contain a supply of film hereillustrated as in the form of a roll B. The side of the magazine has anexposing chamber A and a camera D is applied to the side of the magazinefor exposing the film in the exposing chamber to light.

The magazine is provided with appropriate brackets such as A appearingin Fig. 1 for supporting the roll B, the film from which is run overtheiidler A, into the exposing chamber AF, where it is in position to beacted on by light admitted through the camera D. The magazine ispreferably above the casing A and acts as a cover for said casing. Thefront a of the casing is stationary with relation to the base a, whereasthe sides and back are connected to the magazine and the back is hingedto the base, thus allowing the sides and back of the easing to be swungrearwardly with the magazine for the purpose of permitting access to theinterior of the apparatus.

The rear of the casing has an opening a and below the opening brackets aare attached to the casing. A pan or receptacle a is supported by thebracket a and said pan projects into the casing through the opening (LThe purpose of the receptacle a is to contain a fixing fluid into whichde veloped films are delivered. Under ordinary conditions the lightwould not be sufficiently strong to affect a developed print coming fromthe developing apparatus (to be hereinafter described) but for thepurpose of providing a safe-guard against action of light on a developedprint, a hood cp -is removably secured to the casing in any appropriatemanner. I

The casing contains a tank or receptacle E adapted to receive developingfluid and said tank may have ends a, in which the shafts F and G arejournaled or said shafts may be suitably journaled in operative rela:tion to the receptacle.

The receptacle may be supported by the plates H secured to the base andsaid receptacle has a drain pipe I to which the cock J is connected,said cock extending through the side of the casing. A drip pan K islocated under the receptacle and is provided with a drain nipple 7c,extending through the base. The drip pan is provided to collect thedrippings from the .chains, conveyers and rollers,;to be presentlydescribed. Shafts is extend between the plates H and support the pan Kby passing through apertures in its sides and said shafts carry pulleysoverwhich chains travel. The shaft F has an extension passing throughthe side of the casing on which is mounted a stub shaft 20 (Figs. 5 and9) and said stub shaft is provided with a sleeve 21 supplied with ashoulder 22 at one end and has its opposite ends screw threaded as shownat 23. The sleeve is further provided with a longitudinally disposedgroove 24:. The sleeve is anchored on the stub shaft at any positiondesired through the medium of a .set screw 25. A worm Wheel 26 has itshub rotatable on the sleeve and said worm Twheel has its side recessedto form a clutch member as shown at- 27, the said worm wheel beingengaged by a worm 28, mounted on the shaft 29 of the motor 30, the saidmotor being here shown as an electrically driven type, although I do notwish to be limited with respect to the style of motor employed.

to prevent rotation of the clutch member 31 on the sleeve. In otherwords, the oflice'of the clutch member 31 is to communicate motion oftheworm wheel 26 to the sleeve and as the sleeve in turn is coupled to thestub shaft it follows that the stub shaft will be rotated and as thestub shaft is connected to the shaft F, power is communicated to themechanism for feeding and conveying the film, A spring 34 encircles aportion of the sleeve and has one end bearing against the clutch member31 whereas the opposite end of the spring 34: bears against the nut 35which engages the threads 23 on the sleeve. By means of this nut,tension of thespring 34C is controlled.

Endsof the shafts F and G have sprocket wheels f and g', respectively;and said sprocket wheels are connected by a sprocket chain M, by whichmotion of the shaft F is communicated to the shaft G, and the. shaft Galso has a pinion G meshing with a gear wheel Gr' for driving the rollerA frame N is removably supported above the receptacle and said frame hasa ependthe rotatable drum 0. The drum may be hollow and is preferablycomparatively large with respect to the receptacle in which it issupported for, by this construction. the developing fluid contained inthe receptw-le is displaced and a small quantity of the veloping fluidwill be sufiicient to completely immerse a film as it is carried by thedrum. One end of this drum is provided with a pcripheral gear P, meshingwith a pinion Q, rotatable on a stud projecting from one of the.arms.The pinion Q, is driven by a gear wheel R on a shaft S, the said gearwheel R taking motion from a gear Wheel R, mounted on the shaft G.

The end of the drum opposite the peripheral gear P is recessed to form ashoulder T and said shoulder is engaged by a dog U,

which is slidably mounted on a stud V, the

said dog being pulled downwardly by the spring '1). Under ordinaryconditions, the weight of the dog will be sufiicient to cause it to movelongitudinally, but in order to mg arm n at each end forming supportsforgages said switch. That is to say, when the dog is elevated through itsengagement with the drum, the upper end of the said dog engages theswitch and opens it, thereby cutting out current to the motor but on thede- 7 scent of the dog U and its disengagement with the switch, thespring of the switch operates to cause an engagement of the contacts ofthe switch, thereby completing. circuit through the switch to the motor.

As shown in the drawings, the conductor conduit 37 extends inside of thecase and the conductors 38 and 39 extend 'therethrough and project fromthe coupling 40 tothe terminals of the switch.

41 is a conductor which may be connected to any source ofelectricalsupply and it extends through the insulating box 42 to theconduit 37 the wires from the switch to the motor being extended throughthe conduit 43 and through the box 42. In fact, any appropriate wiringmay be employed for connecting a motor to the source of electricalsupply through which a switch or cutout operatedbv mechanism is employedin connection with the apparatus.

The mechanism is brought to rest at such time as the print is immersedin the developing fluid contained in the tank and the mechanism cannotbetoperated until the dog U is moved out of engagement with the shoulderT. This is accomplished by the lever W which is journaled in the casingand has an arm. W bearing against a stud W on the dog. Pressure on theouter end of the lever results in pressure on the upper *end of the dogwhich will cause the lower -end of the dog to swing out of engagementwith the shoulder. When the lowerend of the dog is clear of the shoulderT, it is free to drop so that its end clears the shoulder T of the drum.The switch will be closed to conduct current to the motor for the pur-'pose of starting the motor as heretofore indicated. The periphery of thedrum being cut away, as explained, also permits the arm X to be movedwith relation to the dog w on the feeding and cutting roller to behereinafter referred to.

The arm X is held normally depressed by means of the spring a and whenthe drum rotates sufliciently to bring the recessed portion thereofunder the arm X, the said arm is depressed until its upper end clearsthe Y end of the dog w. When the dog is released,

the spring forces its nose into engagement with the ratchet wheel Y onthe shaft 3 and hence rotation of the shaft is communicated to thefeeding roller Z, it being understood that the dog w is pivoted on thefeeding roller and that the spring w holds the nose ratchet wheel Y.

' For the purpose of holding-the arm;X;

normally elevated a cam Z'- is mounted on the frame N and may be movedto hold the of the dog normally engagement with the I arm normallyelevated in which position the said arm will hold the dog out ofengagement with the ratchet wheel and the shaft y. maybe rotatedwithout. operating the-feeding roller.

When the print is caused to travel between the feeding roller Z and therollers e, it is punctured at each rotation ofv the feeding roller bythe serrated blade Z on the feeding roller, and the print is thendirected betweenthe two rollers z and 2 and from' there to the interiorof the developing apparatus where the print is delivered to the conveyerconsisting of a chain S and the belt S In operation when the parts arein the position shown in Fig. 4, the cam Z is moved to disengage the armX and the lever W, pressed. tomove the end of the dog U out ofengagement with the shoulder T. The dog will then move longitudinallyand will pass the shouldei' T so that the drum will be free to rotate.Power being applied to the shaft F,'the shaft Gr will be rotated throughthe medium of the sprocket wheels and chain and the gear wheel .R,taking motion from the shaft G, heretofore described, will turn the gearwheel Q, and communicate motion tothe drum. When the drum'is rotatedslightly, th arm X descends into the recess of the drum and the upperend of said arm clears the dog w and permits the spring to force thenose of the dog into engagement with the ratchet wheel. By this means,the motion of the shaft 3 which normally rotates-freely in the 'dog w asit is carried around with the feeding and cutting roller Z, and when thesaid dog contacts the arm, the nose of the arm is thrown out ofengagement with the ratchet wheel Y and the shaft y, is permitted torotate independently of the vfeeding and cutting roller. Though thefeeding and cutting roller comes to rest, the rollers z and 2 con tinueto rotate,' drawing the film downwardly and causing the film inengagement with the said rollers a and 2 to be severed from the body ofthe film on the puncture line heretofore referred to. The film thussevered will be delivered to the conveyer of the chain and beltheretofore.

iso

mentioned. The shaft 3 is driven through the medium of the gear Wheel 3meshing with the gear wheel y on an end of the roller 2. The roller Z"is positively driven by a gear wheel a meshing with the peripheral gear2, on the feeding and cutting roller Z, and the rollers z and 2 arepreferably positively driven by being geared together at one end.

The frame N is provided with a roller N which is relatively small,around which a belt or apron travels and it has been found in practicethat a film after having been carried through the developing tank bymeans of the belt or apron and the chains which hold the film on thebelt or apron, said film being saturated, will adhere to the surface ofthe belt or apron to a sufficient extent to cause the said film totravel with the belt or apron from the point of disengagement of thechain with the film, which is at the shaft F until the said belt orapron starts to encircle the roller N, but owing to the abruptness ofthe turn over the roller, the said film will break away from the belt orapi'onand descend by gravity into the pan or receptacle a which containsthe fixing fluid.

The belt may be tightened or adjusted to make it run straight on theshaft F through the medium of an arm 53 which is engaged by the end of arod 55, which rod is threaded in the lug. 56. The end of the tank has aslot F to permit movement of the shaft F. By rotating the rod 55, thearm is raised or lowered and as the shaft F is journaled in the arm, themovement of the shaft afiects the belt which runs over the said shaft.The rod 55 extends through the bottom of the casing in order that it maybe reached from the outside for the purpose of manipulating the parts toeffect the proper adjustment.

In addition to the hand operated means for tripping the dog U, I employa flexible connection 57 run over a pulley 58 and connected to a bellcrank 59 for tripping the mechanism to start the motor. As shown, thebellcrank is pivoted on a bracket 60 secured to one of the legs of thecasing and the said bell crank has another connection 61 which extendsup into the casing and is fastened to a long arm 61 of a bell cranklever, the short arm 62 of said lever acting on the stud W extendingfrom the dog W. Any appropriate means may be provided for pulling theflexible connection 5 I extend the motor shaft 29 into the easing 62 ofthe pump and connect the casing of the pump with the receptacle a forthe fixing fiuid through the medium of the pipe 63. The pipe 63 acts toconduct the liquid from the receptacle a to the pump casing. The pump isof the ordinary centrifugal type and the liquid which reaches the casingis acted on and is forced through the outlet pipe 64 to the sprayer pipe65, which sprayer pipe is provided with a series of apertures discharing approximately horizontally and longitu inally of the receptacle a towhich it is applied. The ends of the sprayer pipe are provided with caps66 which may be removed for the purpose of cleaning the said sprayerpipe.

The holes in the sprayer pipe discharge at about the level of the liquidcontained in the receptacle so that the current occasioned by the liquidcatches the film as it is descending into the receptacle and acts onsaid film to propel. or carry it rearwardly in the receptacle and, atthe same time, a current of liquid acts on the coated surface of thefilm and on the top of said film, the said action tending to submergethe film in the receptacle. It has been found in practice that as thefilm descends into the receptacle, the liquid emitted from the sprayerpipe straightens it and causes it to float rearwardly of the receptacle,as stated.

In Fig. 11, I show a hand operated device in which the belt 67 or otherflexible connection is driven by the rotary member 68 which rotarymember is mounted on the shaft 69 corresponding with the shaft Fheretofore described. The pump 70 has a pulley 71 from which theflexible connection is run and the pump is in communication with thereceptacle'a by means of the pipe 72, which pipe acts as a feeding pipefor the pump, whereas the discharge pipe 7 3 of said 74: which is of thesame construction as the sprayer pipe 65 heretofore described.

WVhile I have stated that the spraying apparatus was designed to spreadthe film after it has been delivered into the receptacle a, I have foundit desirable to provide mechanically operated means for spreading'thefilm which mechanically operated means may be used independently or inconjunction with the spraying apparatus. I have attained verysatisfactory results by using them in conjunction with each other and inthe relation shown in Figs. 2, 3, 4 and 6 of the drawings.

The mechanically operated spreading means heretofore described is shownin the drawing in the form of lengths of material which are bent to formthe spreadmg members proper, each of which lengths of material ispreferably bent whereby the arm 7 is formed and in which an intermediatestraight portion 76 is j ournaled in a bracket 77, which bracket 77 isattached to the easing; theend of the length of material being formedinto a crank 7 8 above the said bracket. As shown in the drawings onebracket and spreading member is attached at each side of the opening inthe casing. A

spring 79 encircles the portion 76 and has a her in the bracket in orderthat the' arm may travel from the position shown in full lines in Fig. 6to the position shown in dotted lines in said Fig. 6, as willbe seen byan inspection. thereof. The arms swing outwardly in opposite directionswhen power is applied to the cranked end of the member and in order toswing the said arms oppositely, it is necessary that the crank of onemember be at an angle with relation to its arm different from the angleof the crank of the other member withrelation to the arm of the lastmentioned member. The relation of the parts just mentioned is shown inFig.

6 and thecranks of the members are con-.

nected by a thrust rod 80 which thrust rod has a link 81 pivoted to itintermediate its length by which motion is communicated to the saidthrustrod. The outer end of the link 81 is pivoted to a collar 82, andthe collar in turn is connected to an oscillating lever 83 which isjournaled in a bracket 84 attached to the casing. The end of the os-'cillating lever remote from the collar is moved in one direction by .acam 84* projecting from the side of the spur wheel 85 which spur wheelis mounted on a stud 86' anchored to the casing in any appropriate way.The spur wheel 85 is driven through the medium of a pinion 87 which ismounted on the stub shaft 20, and therefore as the developing apparatusis operated, motion is communicated to the mechanism for spreadin thefilm. .An inspection of Figs. 6 and 7 will show that the lever is movedby the cam 84 against the action of the springs 79 until the end of thecam is reached and at which position the arms 75 will have traveledoutwardly as shown in full lines, Fig. 6,

the said arms being returned immediately thereafter to the dotted lineposition ofFig. 6 under the influence of the springs when the said leverhas been released by the cam. The members are in such relation to thedeveloping apparatus that the arms operate to spread each film as it isdelivered to the receptacle a This same apparatus maybe employed inconnection with the hand operated machine shown in Fig. 11, by providingthe shaft 69"with a pinion similar to the pinion 87 and duplicating theparts of the spreading apparatus heretofore described.

The throw of the lever 83 may be regulated by moving the collar 82thereon nearer to or farther from the pivotal point, the said collarbeing provided with a set screw 88, to effect the desired adjustment. 7

In addition to the mechanism for spreading the film, I provide means for"submerging the film which submerging means acts in conjunction with theother apparatus for developing and spreading'it. The embodiment of thesubmerging apparatus here shown consists of a frame 89 which'is aproximately rectangular in plan with the ,means for receiving means.

exception that the forward portion thereof,

stands slightly at an angle with relation to the rear portion thereof.The frame 89 has.

side extensions 90 each of which is bent in order that therearend'thereof will stand at an angle to the front portion thereof and therear end of each extension is provided with a socket 91, designedtoreceive an arm 92 projecting from a shaft 93. In order to provide for ayielding action of the frame 89, the arms 92 are coiled around the shaft93 as shown in Fig-10. While this construction'is not necessary, it hasbeen found in practice to be quite desirable as it absorbs vibration.The shaft 93 is journaled in the side of the casing in any appropriateway and is provided with an arm 94 which extends into the path of travelof a stud 95, which projects from the dog U, thereby causing theoscillation of the frame as the dog is reciprocated. As the said dog Urises and falls by reason of the operation thereof as heretoforedescribed, the frame 89 with the shaft 93 has a pivot. The relation ofparts shown in Fig. '2, indicates that with an upward movement of thedog U, the arm 94 will be moved upwardly, thereby partially rotating theshaft 93 before causing the descent of the frame 89 into the receptaclea as shown in Fig. 4:. Thus any film that has been delivered to thereceptacle 84 will be pressed into the liquidv contained therein.

While I have termed the means for immersing the film a frame it is to beunder-- stood that any plunger of a skeleton or solid type designed byits weight or by pressure apphed'to it toimmerse a film shall beregarded as falling within the scope of the term.
